rLOCK OR LATCH CASE.

SPECIFICATION forming part of Letters Patent No. 623,296, dated April 18, 1899. Application filed February 20, 1899. ASerial No. 706,293. (No model.)

To @ZZ whom, t may concern:

Be it known that I, HENRY G. VOIGHT, a citizen of the United States, residing in New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Lock or Latch Cases, of vwhich the following is a specification.

My invention relates to improvementsin cases for locks or latches; and the objects of my improvement are simplicity and economy in construction with efciency and neatness of appearance in the article.

In the accompanying drawings, Figure lis a plan view ofmy lock-case. Fig. 2 is a front elevation of the same with the cap-plate removed. Fig. 3 is a detached front View of the portion of the cap-plate that abuts against the face-plate. Fig. 4 is an elevation showing the inner edge of the case. Fig. 5' is a sectional view, partly in elevation, of a portion of the case on the line a: .it of Fig. 2; and Fig. (3 is a sectional view on the line fz/ y of Fig. 2.

A designates the body of the case, and B the face-plate, the same being secured to each other by means of the shouldered fasteningplates 7 and bent-over lugs 8, which lie in a shouldered recess of said plate in accordance with the patent to Burgess, No. 612,397, dated October 1S, 1898. Instead, however, of forming the side flanges 1I of the case-body with interlocking recesses to hold the outer or faceplate edge of the cap-plate C in place I carry the edges of the side flanges to the face-plate on a line that is flush with the face of the bent-over lugs S and make the confronting edges of the metal in the cap of corresponding form, whereby a neat finish is given to the upper and lower edges of the complete case.

In the lock-plate of the case-body A, at or near the face-plate edge, I secure the holdingstud 9, in the form of a spring-plate. notched atboth edges, as at 10, Fig. 5, in the plane for the portion of the cap-plate that abuts against the face-plate. The said holding-stud may be attached to-or formed on the said lockplate in any proper manner; but I prefer to form a tenon on its inner end and rivet the same in a hole in the back plate of the case, as shown, and in order to make said hole a little inside of the outer edge of said lockplate I form an offset 11 in said stud,as shown. I also prefer to make said stud of met-alhaving some degree of elasticity and to so set it in place that when not engaged by the capplate it will stand off a little distance from the inner face of the faceplate, as shown in Fig. 6. I also form the side fiange 12 at the inner edge of the case-body a little wider than the adjacent portions of the side flanges at the top and bottom edges of the plate, as shown in Fig. l, and with a central notch or recess 13, as shown in Fig. 4.

The cap C is provided at the edge that abuts against the face-plate B with a notch or recess 15, Fig. 3, the width of which notch corresponds with the width of the neck between the notches 10 10 of the holding-stud 9, while the said notches correspond with the thickness of the metal forming the cap in the sense that the same may interlock with each other, as hereinafter described. The top and bottom side flanges 16 and side flange 17 of the cap have their edges fitted to match the confronting edges of the corresponding anges on the case, whereby the innerends of the side flanges 16 of the cap shut inside of the flange 12 of the case and form abutting shoulders, as shown in Fig. l. I also provide the flange 17 of the cap with a projection 1S, thatts into the recess 13 of the ange 12 of the case to assist in holding the cap in position on the case-body.

Vhen the cap-plate is detached,the holdingstud stands slightly away from the face-plate, as shown. register with the body of the case, and the metal in the cap above and below the notch 15v is entered into the notches l0 of the holdingstud 9. The cap is then forced toward the face-plate, carrying with it the said stud to bring it closely to the face-plate, and then the inner end of the cap is forced into place, as shown in Fig. l. The spring holding-stud acts in opposition to the abutting shoulders at the inner edge of the case as formed by the anges 16 of the cap and the flange 12 of the case-body and causes sufficient friction to make the cap stay in place until it can be secured by the ordinary holding screw or screws. It will be noticed that the'holding- The cap is placed in position toy IOC) stud, which is in the vertical middle of the cap-plate, not only holds the cap on, but it also holds the cap from being bent inwardly toward thelock-plate of the case-body, Whereby I am enabled to dispense with the post ordinarily employed to keep the plates of the case apart. holding end normally a short distance from the face-plaie is preferred7 it is evident that the interlocking of the cap andholding-stud would be the same if the said post were normally placed in contact with the faceplate.

It is apparent that some changes from the specific construction herein disclosed may be made, and therefore I do not Wish to be understood as limiting myself to the precise form of construction shown and described, but desire the liberty to make such changes in Working my invention'as may fairly come Within the spirit and scope of the same.

lVhile a spring-post set with its Y l claim as my inventionl. A lock or latch case cent to its face-plate, the notched holdingstud, in combination` with a cap-plate having its face-plate edge fitted to interlock with said holding-stud, substantially as described.

2. The combination of a latch or lock case body and cap-plate, with the spring holdingstud mounted on said body normally at a slight distance from the face-plate, interlocking devicesgfor connecting said stud and adjacent portion of the cap-plate, and abutting shoul ders for the 'cap and case-body at the inner edge of the case, the said spring holding-stud acting in opposition to the said abutting shoulders, substantially as described.
